- adj. producing the sensation of heat when applied to the body
Sorry, no etymologies found.
The animal experimented upon to be supplied daily with a weighed quantity of food, the composition and calefacient value of which had been accurately determined.
The gases, vapors, and liquid and solid egesta thrown off from its body to be collected, analysed, and the calefacient  value of the combustible portion of them to be determined.
These figures show the relative calefacient, or heat-producing powers of the different foods named _outside_ the body; but there is some doubt as to their having the same relative values when burned _within_ the body.
Ammianus Marcellinus, Hunni semicruda cujusvis Pecoris carne vescuntur, quasi inter femora sua & equorum terga subsertam, calefacient brevi.
